OPERA plus 50-100-300-500W FM 87,5÷108MHz transmitters use amplifiers with 6^ generation LD-Mos technology, practically unbreakable.
The technical solutions adopted by our engineers are focused to assure energy saving (among the lowest) and high reliability. Settings, protections, telemetry are totally microprocessor controlled. The installation and the maintenance of the equipment are respectively very fast and easy.These fully protected transmitters are indicated for use in unmanned stations.

Andrew Wroblewski –
Utterly amazing piece of kit, and came within 14 days. We were starting to panic, because all other transmitters were just not available for months, and then Dave at transmittersRus, got these wonderful TEM transmitters for us within 14 days. One of the most advanced and solid transmitters ever, with every facility you could ever want. Thanks to Dave at transmitterRus we were able to meet our deadline for our community radio station, otherwise we would never have got started for months. Thanks again to great service and mega advice from Dave.
